A poll on Monster failures and non-failures

[jhautz]

2 MMMs. 2 dead fans. So far batting 1000. Both have less than a couple hours of run time.

Here is my solution. See picture below.

I'm pulling the dead fan and strapping a 25mm fan to the top over the fan hole and letting it blow into the case. The 25mm fans I was using on the MM and R1Pro are much more robust. I wish I could remember where I got them. I bought a lot of 10 for a good price like a year ago adn now I cant remember where I got them. Anyway, the 25mm fan moves more air than the 30mm fan that came with it. I can feel stronger air flow comming out the side vents of the MMM than with the stock 30mm fan.

Not pretty, but it works.

Do you know if Castle uses the same thermal epoxy on the MMM that they do on the MM? The MM stuff is pretty easy to remove. I want to simply replace the existing HS for a taller one and cut away the top of the case to allow more unrestricted airflow.

Wouldn't the 25mm fan fit in the stock fans spot?

I asked Joe at CC for a replacement top case so I could mod it for better natural airflow over the heatsink so I dont need the fan. He told me not to do it cuz the esc will fail. Seems like a company line to me cuz I think it should handle it if I could run my MM without a fan on the same setup. but, thats what he told me.
But at this point I'm not willing to void my warantee untill they get all the bugs worked out of this stuff. You just never know when it will need to go in for service and the hacked up case would pobably be a big red flag.

No. The 30mm fan is only 7mm thick and the 25mm fan is 10mm thick. The case wont close with the 10mm thick fan inside.


EDIT: Another note, the case itself seems to be another weak point IMO. I have opened one of them a few times now to replace fans and check thing out etc... and the littel clips that hold it closed are already startign to not hold so well any more. If I have to replace the factory fan every 2 hours of run time those little clips that hold i closed are never gonna last. I already have a zip tie wrapped around it to hold it all togheter and make sure the top doensnt pop in some sort of crash on the track.

Yeah, sounds like a line to me too. A taller heatsink with less casing around it would be almost as good as an enlosed design with a fan (if placed right). Would also allow easier temp readings.

If the ESC "will fail" without the fan, I don't want it. So, for those who have already had fan failures, how many of those ESC failed?

jhautz - dude, I love the new look . . . it's like the Abe Lincoln of ESC's!

Good solution though. And I would have to agree with Brian's direction about the poll. More options would be nice, but I guess it still accomplishes the goal - people talking about it.

My failure wasn't due to anything like the BEC or the fan - it was because my casing came apart every time I wrecked and eventually a wire separated from the board. So I would agree with the comments on the casing. I think it needs a revision. I would love to see it be basically like the old Mamba Max with the solid casing at the bottom and the exposed heat sink. Or something like the MGM which allowed you to secure the whole unit with threaded holes at the heat sink. I loved that setup.
